i don't know i can help you but i can say i've been there. spiralling down and down, and everything is harder and harder. it's worse when there are real problems in your life that there's no easy fix for.
can't make money magically appear
cant magically make relationships work
cant magically suddenly feel better.
for me, each time i've gotten this low, i get desperate, and i reach out, for anyone to hear me, anyone to listen. and somehow talking about it and having someone on my side, that gets that my problems are real has always made it better. i dunno why. it just feels better to not be alone in this impossible battle.
if you can, get a counsel or, just for the validation that you are right and things really really suck.
i have nothing else, i'm close to rock bottom myself, too many things keep piling on and my ability to shrug it off and keep going has dwindled. i just want the world to leave me alone. just stop. i know with time and space to heal and just be me and do things for me i could get better... but not if i can't get off this merry go round.
